Product details
Overview
HMC375LP3 from Analog Devices is a GaAs PHEMT MMIC low-noise amplifier optimized for 1.7–2.2 GHz cellular basestation front-end receivers, delivering 0.9 dB noise figure, 17 dB small-signal gain, and +34 dBm output IP3 at +5 V / 136 mA with 50 Ω input/output matching. It serves as the first-stage LNA in GSM, CDMA, and W-CDMA receiver chains where high linearity and ultra-low noise are critical.
For engineers reviewing the HMC375LP3 datasheet, HMC375LP3 pinout, HMC375LP3 application, or HMC375LP3 equivalent, key selection criteria include its 1.7–2.2 GHz bandwidth, stable gain vs. temperature (±0.021 dB/°C), minimal external component count, and compatibility with RF front-end designs requiring <1 dB NF and >33 dBm OIP3 under single +5 V bias.
Technical Context
The HMC375LP3 integrates a two-stage GaAs PHEMT amplifier architecture with on-die biasing and internal DC blocking, enabling broadband operation from 1.7 to 2.2 GHz without external tuning. Its input is matched via integrated 13 nH inductor to ground, while output uses AC coupling and 50 Ω termination.
Thermal design relies on direct soldering of the exposed paddle and all ground pins to PCB RF ground, with thermal resistance of 64.1 °C/W (channel-to-paddle) and max channel temperature rated at 150 °C. Absolute maximum Vdd is +8.0 Vdc across Vdd1/Vdd2 pins, though typical operation is +5 Vdc.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Figure | 0.9 dB typical @ 25°C - enables high sensitivity in weak-signal cellular base station receivers |
| Small-Signal Gain | 17 dB typical @ 2.0 GHz - provides sufficient first-stage amplification before mixer stage |
| OIP3 | +34 dBm typical @ -20 dBm/tone - supports high dynamic range in multi-carrier CDMA/W-CDMA environments |
| Supply Voltage | +5 Vdc - simplifies power architecture by eliminating need for dual or negative supplies |
| Supply Current | 136 mA @ +5 V - defines 680 mW DC power dissipation, requiring thermal management via ground paddle |
| Frequency Range | 1.7–2.2 GHz - covers full GSM (1.8–1.9 GHz), CDMA (1.9–2.0 GHz), and W-CDMA (2.1–2.2 GHz) bands |
| Input/Output Match | 50 Ω matched - eliminates need for external matching networks in standard 50 Ω RF systems |
Pinout & Package
The HMC375LP3 is housed in a 16-lead LP3 surface-mount package (3.0 × 3.0 × 0.85 mm) with exposed thermal paddle. All ground leads and the paddle must be soldered directly to PCB RF ground per Analog Devices' land pattern guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 4, 6–10, 12, 14, 16 | No Connect (NC) | Internally unused; may be tied to RF/DC ground for shielding or thermal conduction |
| 2 | RFIN | 50 Ω matched RF input; includes internal 13 nH shunt inductor to ground for broadband match |
| 5 | ACG | AC ground node requiring 0.01 µF external capacitor to ground for low-frequency bypass |
| 11 | RFOUT | AC-coupled 50 Ω matched RF output; requires external DC blocking capacitor in series |
| 13, 15 | Vdd2, Vdd1 | Separate drain supply pins; each requires choke inductor + bypass capacitor per application circuit |
| GND (paddle) | RF/DC Ground Reference | Exposed thermal paddle - must be soldered to solid ground plane with multiple vias for thermal and RF integrity |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low Noise Figure | 0.9 dB typical enables detection of weak signals in dense interference environments like urban macrocells |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC618LP3E | Lower 0.55 dB NF but narrower 0.6–1.0 GHz bandwidth; higher 20 dB gain | Optimized for PCS/UMTS lower bands, not 1.7–2.2 GHz | Select only if primary requirement is sub-0.6 dB NF and frequency coverage aligns |
| QPL9057 | 0.65 dB NF, 19.5 dB gain, 1.7–2.2 GHz coverage, +5 V / 110 mA, integrated active bias | Higher integration reduces external components; slightly lower current draw | Prefer for new designs seeking simplified biasing and tighter NF, accepting minor gain trade-off |
Compared with HMC375LP3, the HMC618LP3E offers superior noise figure but lacks 1.7–2.2 GHz coverage, while QPL9057 delivers comparable bandwidth with lower NF and simpler biasing-making it suitable for next-gen FWA and small-cell deployments where layout space and thermal headroom are constrained.

FAQ
What is the operating temperature range for the HMC375LP3?
The HMC375LP3 is specified for continuous operation from -40°C to +85°C ambient temperature. Its internal channel temperature is rated up to 150°C, and thermal resistance from channel to ground paddle is 64.1 °C/W - requiring proper PCB grounding of the exposed paddle and surrounding ground pins to maintain reliability within this range. Derating begins above 85°C at 15.6 mW/°C.
Does the HMC375LP3 require external matching components?
The HMC375LP3 features internally matched 50 Ω input and output ports, minimizing external components. However, Pin 2 (RFIN) uses an integrated 13 nH inductor to ground, and Pin 5 (ACG) requires a 0.01 µF capacitor to ground. Pins 13/15 (Vdd1/Vdd2) need choke inductors and bypass capacitors, and Pin 11 (RFOUT) is AC-coupled - so DC blocking remains necessary externally. No impedance transformers or stubs are needed.
What is the absolute maximum supply voltage for the HMC375LP3?
The absolute maximum drain bias voltage for the HMC375LP3 is +8.0 Vdc applied to either Vdd1 (Pin 13) or Vdd2 (Pin 15). However, the device is characterized and optimized for +5.0 Vdc operation, drawing 136 mA. Operation at +4.5 Vdc or +5.5 Vdc is supported with minor gain/NF/IP3 shifts - but exceeding +8.0 Vdc risks permanent damage to the GaAs PHEMT structure.
How does the HMC375LP3 compare to the HMC375LP3E variant?
The HMC375LP3 and HMC375LP3E share identical RF performance, pinout, and electrical specifications. The difference is RoHS compliance: HMC375LP3 uses Sn/Pb lead finish and has MSL3 rating with 235°C peak reflow, while HMC375LP3E uses 100% matte Sn, RoHS-compliant packaging, and MSL3 with 260°C peak reflow tolerance. Both are drop-in replacements electrically and mechanically.
Is an evaluation board available for the HMC375LP3?
Yes - Analog Devices provides Evaluation PCB 107726, designed specifically for the HMC375LP3/HMC375LP3E. It features Rogers 4350 substrate, 50 Ω microstrip routing, SMA connectors (J1–J2), and optimized placement of required passives (L1 = 13 nH, L2 = 33 nH, L3 = 24 nH, C1 = 1000 pF). This board enables rapid prototyping and RF performance validation without custom layout effort.
